I have just about got my head around how JavaScript frameworks like Backbone.js and Spine.js deals with the client-side state of a data model in regards to updating views etc. I am looking to build a web application with Backbone that syncs its model with a database. Most of the examples out there use Ruby, but I am currently much more comfortable writing PHP. I have experience with MySQL and MongoDB.
I am looking for a very basic, stripped down version, of a RESTful web application that uses Backbone and syncs with a database through PHP. I have found tutorials like this one and this one, however, even these are too complex for me to learn from.
It would be nice to have a very basic example. For example, a HTML form input, and a list. Enter into the input to add to the list. Of course, this data model will be synced to a database (preferably MySQL). Would anyone be able to provide me with the code for this example? I am comfortable with using a PHP framework like Slim also.
Once I understand how to sync created data to a database, I can then begin to grasp the rest (CRUD). I have seen very few tutorials out there on how to this at a basic level with PHP, so hopefully any support will benefit others too.
Have you seen this one from net.tuts? I think they will post a new tut soon with more details
Edit
And there are at least 2 similar questions here actually:

I have given the new project to complete where i have separate components which talk to each other via services calls
They are not linked directly.
The technical head wants to build the entire frontend in ExtJS or jquery and then use JSON to load the data. I mean all forms , login etc will be JSON.
Now i ahve not done anything like that that. I mean i have always generated forms , data from server side controllers and views. like PHP or Django python.
I want to know that is this way good or achievable because i don't want to chnage things after spending time initially.
but is its the good way then i can start with it
I'm working on a Django project for the past six months, where I'm using Django for the backend service, returning only json responses, and the frontend code is completely separate.
jQuery by itself would result in unmaintainable code, even on a smaller scale, so you definitely need a high level frontend framework. I settled with Durandal.js, which includes:
Knockout.js for the ui bindings
Sammy.js for view routing
Require.js to modularize the code
I think it was a good choice at the time, and I feel very productive with that tech stack. If I were to start from scratch again, it would be very likely a similar stack.
As for ExtJS, it's a component/widget based framework, which philosophy I don't very much like, I saw the future, and it wasn't written in ExtJS :)
Although I see AngularJS and EmberJS as the titans that will very likely win the battle of frameworks, at least for now.
So I have a simple jQuery Mobile site interfacing with a MySQL database via PHP. Users orders are queried initially, then updated using the mobile web interface. I am not using any PHP framework, just 7 or 8 PHP files I've written for retrieving, updating, creating, and deleting order records.
As I begin to develop the Android and iOS applications, I realized it would be beneficial to have a PHP backend framework that can handle requests to create/read/update/delete my orders and users records from any of the 3 sources without caring which one it is. I want to create a layer of abstraction between the server side database handling and each of the 3 mobile interfaces. I envision being able to make a POST call from the client side, passing a TYPE argument and a JSON array of the data to a generic page like /myserver/mRequest.php, which would determine what to do based on TYPE and handle the processing, returning a STATUS variable and a JSON array of data back to the client.
Is there a good (preferably free) PHP framework that will help layout the backend? I've looked at Zend and a few others, but they seem pretty heavy and intended for desktop sites. I want to minimize the number of calls to the server as well as the amount of data thats sent back and forth (we all know how slow Verizon 3G is).
I'm hoping theres some lightweight framework out there that can be a skeleton for me to organize CRUD functions, check for null values, handle MySQL errors, etc...
If not, a guide to developing a PHP mobile backend would be the next best thing.
Note: I apologize it there is a thread already asking this, but I couldn't find one that I thought fit.
Almost any of the major free frameworks would do the trick, Symfony for example handles regular page templating for your jQM pages and handles ajax nicely too.
However, if you only require the framework for the AJAX handling and something broader, you might be advised to develop your simple scripts, with less effort and less of a learning curve (of course, the learning may be part and parcel of your plan).
Another option is a Data Abstraction layer between your scripts and your PHP, this would give you greater flexibility in terms of your data changes, but not burden you with a hefty framework in between. Propel and Doctrine are worth a look and are often used as part of web frameworks.
I personally really like CodeIgniter, which is a very clean and powerfull lightweight PHP framework with easy database-access.
Just have a look at it.

I'm developing an iPhone APP and need to implement also an Web Service.
First of all I'm not a Developer and never made something big in PHP, Objective-C, xCode.
My PHP knowledge isn't also good. But let's start with my Environment.
iPhone APP (xCode 4.2, iOS5), PHP Web Service, MySQL DB
I was researching the WEB and most People tend more to REST than SOAP. I think i see also the advantages of REST (using of simple HTTP Verbs (get, post, delete etc...), but that's not the main point here...
I think I understand the main goal of the REST Architecture and tried to make a little concept with an URI and Verb Mapping. Here just a simple example of the mapping:
/location/{location_id}/product
/location/{location_id}/product/{product_id}
Both are GET operations who should get me ether a single product or all products of a location.
How would a simple PHP REST Web Server look like with these functions?
Another part should implement a User Authentication from the iPhone. Somehow i need to store the user session, right now I don't have any idea how to make that. The goald is that if only a user is logged in, he could review the product.
Now I've researched also the Web but couldn't find an easy step-by-step Tutorial.
Do you know any good Tutorials which will help me achieve my goal? :)
A lot of people prefer using PHP Frameworks like ZEND. This seems very interesting, but it seems like a big package with a lot of modules.
Does someone know exactly which Modules are needed to get my Web Service working?
This is quite a good tutorial, it uses the codeigniter framework which makes the learning curve a bit steeper but makes it a lot more powerful in the long run.
http://net.tutsplus.com/tutorials/php/working-with-restful-services-in-codeigniter-2/
If you want to build this the custom way it's actually very easy to do if you want to return information in the JSON format especially for php5 which is generally well supported amongst hosts these days.
Essentially the steps are like this:
Pass in product id via url and retrieve using GET i.e. service.php?product_id=10
Query database and return data for product id that was passed in
Store returned data in an array
Set header content-type to application/json
json_encode the result (json_encode)
That way when you call that url in a browser you will get a nice JSON formatted array result in a key:value pair manner. And as of iOS5 json parser comes with the framework (for earlier versions SBJson is a good framework to use (SB JSON))
I'd like to query a MySQL database via a RESTful service with the middleware being PHP. I'd like the output to be JSON. I'm a beginner in those areas. Are there any frameworks or scripts that can do this without requiring you to be an expert? I don't have a problem stringing a few scripts together if they can work.
Or, if it can be done much simpler without using REST (i.e. query parameters), that's fine.
In the end, I want to have an iPhone app fetch this data and have it returned via JSON. No javascript will be involved.
You can convert a MySQL result set to JSON easily: http://phpclasses.nlared.com/browse/package/3195.html
For a RESTful interface, basically any hosted PHP script can function as a REST interface for your application.
Check out this project: http://phprestsql.sourceforge.net/
On this site you will find a RESTful
interface (written in PHP) to a
database (a MySQL database, but that's
not important). Below you will find a
interactive tutorial that will get you
accessing, adding and deleting rows
from our database via our Javascript
powered REST browser.
The PHP shouldn't necessarily be your middleware in your situation, you'll have to build your "RESTful" service somehow, whether it be with PHP or any other language. You don't have to be an expert, but I think CakePHP has some of these capabilities.
Maybe explain in more detail what you want to do.
Update
Try this out:

Not only is CakePHP easy to install and use, it's also easy to extend.

i'm developing a web application that focus heavily on ajax. the whole application is just on one page except for the threads that are in traditional pages so they can be indexed.
so i have to have very structured JS-codes and i wonder if they are any frameworks out there that are for ajax-based applications.
eg. codeigniter, cakephp and others i have read about dont focus on this. they just organize regular php code according to mvc.
cause my code starts to be very messy (especially the js code) and i really need some structure here. is there a way to have same mvc + oop structure in javascript? i never heard anyone talking about it. even if i put js codes in separate files, one for each page for example, there are a lot of lines and i feel lost and crunch whenever i have to add some new functionalities.
would be great with suggestions and ideas how to structure this up!
I think you have the wrong mindset about this.
AJAX-heavy sites or applications aren't that much different form their Web 1.0 counterparts in their underpinnings. You still have the same basic components: HTTP Requests and responses. It's just that with AJAX you rarely request a full HTML page. Most of the time you're requesting snippets of HTML, XML, or JSON.
So, just because you'll have a web site/app that is 90%+ AJAX driven doesn't mean you need to throw away existing conventions like MVC and look for something new.
And most modern frameworks have plenty of AJAX stuff baked in: ZF, symfony, cake, etc.
EDIT
I don't know of any framework, PHP or JavaScript, geared towards what you are asking. That being said, you might get something out of watching High-performance JavaScript: Why Everything You've Been Taught Is Wrong, Designing the Rich Web Experience, and High Performance Ajax Applications, even though they're a couple years old now.
Also, consider digging into projects that are AJAX heavy and seeing how they tick. ExtJS and jQuery UI based applications would be a good start.
You might check out Zephyr. Never used it myself, I just know that it's mainly for AJAX apps.
The symfony framework is great for Ajax, and they have a well-thought-out approach involving the MVC backend and your JavaScript code, especially the popular JavaScript libraries like JQuery and Scriptaculous.
It would be worth your time to read the chapter on Ajax in the Symfony Askeet tutorial just to see how someone else has done it. Also, the Ajax chapter in the older symfony book outlines other uses besides the search autocomplete feature shown in the Askeet tutorial.
You want something special for ajax, that can integrate into other frameworks? try, Cjax : http://cjax.sourceforge.net/examples/ , good for heavy ajax, with ajax controllers and routes.
I was told to put in more details so here it goes...
It allows you to write ajax in the PHP side, it gives you many tools that you can use to make your development experience a smooth ride. It also saves you tons of time from re-inventing the wheel
Cjax comes with over 70 examples/samples/docs and APIs that can let you do amazing things with a single line of code, that otherwise would take you hours or days, or even weeks!. You know, the usual success message, to lightbox, submitting forms with ajax, and uploading files with ajax, you know - the usual stuff that you would use in your application or website, has become an e-cosystem of ajax functions.
Cjax consolidates all your ajax code in a single place. Making your code more secure. Cjax also has only one point of access. Making your application or website very secure. Cjax lets you use classes and routes your ajax calls through a dispatcher to reach your ajax controller. Includes a callback system, that lets you do ajax requests when the page loads, but also, when you trigger your ajax request once on the server, it lets you run more ajax code, and interact with your application or website right from the back-end, right from your controller. This gives you the freedom to go back and forth, from one ajax method to the other, working in harmony. Also includes a way that you can maninupate all the elements on the page, right from the back-end, all done within one ajax call.
Cjax is a piece of machinery to build ajax features . Uses unconventional methods to push the bounderies in allowing you to just write very few short lines of code .
Cjax has the power to allow you to to call and use your existing JavaScript, without making changes to it. It really lets express yourself in the way that you want to express. You have old, or new custom JavaScript, execute it with Cjax - you can pass data to your existing functions, instanciate them, right from the back-end. You use other 3rd party libraries or code - no problem. Cjax lets you execute it, and pass data to it, right from the back-end, you can call them as many times as you want, no limit, only the sky. You can pass from simple strings, or integers, to entire arrays or objects. Guess what, As a matter of fact, that is what Cjax's plugins are, 'plugins' is just a formality, but what they really are - custom code ran with Cjax. If you run your custom code, you already built a Cjax plugin!
Cjax code is simple easy to understand, and uses convention over configuration approach to do the most, with less.
I will give you some examples:
Pagination: http://cjax.sourceforge.net/examples/pagination.php
autocomplete, ajax uploader, etc.
Check out Yii or Zend Framework.
I build apps like these. My architecture:
Server-side: Zend Framework
The PHP code is exposed as a set of JSON-RPC web services. The web services are implemented with Zend_Json_Server, and don't do anything HTML generation (all UI is handled client-side). Because of this, the server-side code is fairly limited (database interaction, session management, and security).
Client-side: ExtJSThe code is bootstrapped from a single PHP page hosting the ExtJS framework, and after that dynamically loads javascript components as separate files on-demand. Each javascript component calls a web service to initialize itself and load/save data. There are also special translation files (dynamically generated from PHP) to patch the class prototypes with translations.
In this approach the web services do not send back any sort of pre-generated HTML. They are data bridges, shuttling records back and forth. All UI construction is done client-side. Zend_Json_Server exposes a PHP class as a service (the methods of the class are the functions of the service). This keeps the PHP design clean, and offers ultimate flexibility in UI. The mobile front-end is built around the same classes as the RIA front-end. It's also easy to build other apps on top of the same web services (e.g. a windows app, an iphone app, ...). The minimal amount of PHP code keeps server overhead low.
If I were you I would focus more on what javascript framework you're using than on a PHP framework. If you're going whole-hog ajax (without basic html fallback), there's simply no point in getting the server involved in generating the UI (it just slows the app down).
